Assassin has advantage on attack rolls if creature has not had its turn. Attack rolls does not specify weapon attacks or the attack action. I understand that to mean a spell attack would be made at advantage. Is that correct?
Yep. The auto-crit also applies to spell attacks. It works nicely with good scaling attack spells like scorching ray, or a nice hex + Eldritch Blast combo.
You get to use the Advantage on spell attacks, but you don't get to add Sneak Attack, just so you know.
Not necessarily. If you meet all the requirements for Sneak Attack you can still be able to use. Sneak Attack doesn't exclude spell attack specifically so it can work with spells attack such as Magic Stone, Booming Blade, Green-Flame Blade.

No but it does specify that you need to attack with an weapon. So all three you mentioned are fine, as long as you use a sling for the Magic Stone attack.

Correct Assassinate applies to any attack rolls, regardless of the attack type.

It is kind of the same as how Steady Aim works with spells also even though its a Rogue optional class feature.
